well I personally can not see how there can be an end, although it is mind boggling how it could be infinite but that is only because we have never seen something infinite.

The universe is sort of growing at the speed of light because of the light travelling outwards away from it's source

It may even be a singularity (consider the experience of the photon travelling at C) and what we perceive as dimensions is just that a perception of some change of parameter of said singularity.

Nicely put. Makes me think tho that it's funny how close that comes to age-old mystic thinking that everything in existence are just different aspects of one underlying truth or deity if you wish.

Problem is that even if it is true, which I do not rule out, it does not tell us much more than that... it does not explain anything, I'm afraid. And maybe it cannot be known, by us at least, since we are bound to a limited number of those dimensions, and get into trouble and headaches if we try to imagine more of them at the same time than we have fingers on our hand. Like chickens hardwired only to be able to count up to four or so. To them anything after that it just 'many'.

Our universe(or space) is just like a balloon.If you(or light) starts travling from one point, then you can go around and around forever. In this sense, our universe is infinite, but just like a balloon is finite,our universe is also finite.For more detailes,one can check "A breif history of time" by Stephen hakwins.

This is a theory to explain the uncomprehendable. Those who want to opt out may do so until the next uncomprehendable theory surfaces.

Hawkins believes that gravity has formed a bubble of a universe but has nothing to say about what is beyond, because in his world there is no beyond. We are a bubble in the middle of nothingness, and we cannot comprehend anything outside of our bubble.

Argument with Hawkins is not possible because of the way the rules are written. It is kind of like being told no by your mother and you ask why and she says simply "because".

Personally, although the math is so very tidy, I hope for something a little more meaningful than being a hicup in nothingness.

A worm crawling on the surface of an apple, may think it lives in an infinite universe.  How do we differ from this, living in 4-d space-time?

[David Sparkman]

A poor analogy, first parts of worms like the insides of apples, I can attest to that as I have found parts of worms inside apples I have bitten (yeech).

Second, it is not man's nature to accept that he cannot know, and cannot learn. Worms are dumb for leaving their parts inside apples (lol).

I'd just like to point out at this juncture that my wife has very nice dimensions.

Men are the same as women.... just inside out !!

the universe is expanding,(we can figure out the rate though it varys in different areas) therefore there is a set amount of space and therefore space is not infinite...  well universes are expanding... so at least within our universe it makes sence.  theory of a multiverse works just like saying from here to the wall is 10 feet  within each unit of feet or inches and so on  there is an infinity there for space is infinite just like that wall there is an infinity infinites and infinity multiverses all stacked on each other....i have been thinking about this all day and searched the web and found this site.... me thinking about this just led to more and more questions and now i am in a frustrated state of trying to figure out the concept of infinity

From the big bang the universe just kept expanding at phenomenal speeds. From then on it will keep expanding until it gets to large and collapses on it's self (some scientists think).

I have heard but am not sure that the universe is about 150 billion light-years wide.

[simeonie (OP)]

well no one actually knows whether it is infinite or not we don't know. I admit there can't be an infinite ammount of mass though because it would mean infinite gravity this the universe collapsing in on itself. BUT there could be a TOTAL vacuum though for the rest of infinitey. I can not understand how there could be an end. I mean if there is an end like a wall or something there must be something on the other side of the wall. Ya know what I mean?

Infinity: a symbol or reality.
1. Everyone knows, that absolute temperature T=0K cannot be reached.
We can only indefinitely come nearer to her.
2. Everyone knows, that nobody can reach
absolute speed of quantum of light  c=1.
We can only indefinitely come nearer to her.
3. But everyone also knows, that only quantum of light goes with
absolute speed  c=1.
It is the fact, it is a reality.
Question: Unless can this absolute movement  c=1 occur in  relative reference frame ?
Answer: No.!
The absolute movement can occur only in absolute frame of reference.
But only one absolute  frame of reference is known  T=0K
(which  is impossible to reach).  
And only in her quantum of light can move with the absolute speed  c=1.
 And it is also reality.
But what can tell quantum of light about his travel in the parallel world?

We can't actually say that. All we can say is that the observable universe is expanding. Maybe beyond that it is actually static or even contracting.

I think this is one of those questions that cannot be answered because there is just no way of proving.
